Both will build an application that can be run on 10.4 or later. The
difference is that, with "a", you will also (weak-)link against the
symbols only available on 10.5 and later.
If you don't need to use any Leopard-only features, it's probably
simpler to go with option "b".

If you click once on the value in the build-settings window, and wait
for about a second, you will get a simple text field in which you can
enter literal values (instead of having to deal with the check-boxes).
